It is well known that the breaking load of a product made from GHas is generally lower than that which the Brseug theory ought to have "if" takes into account its cross-section. It is also known that the breaking load can be greatly increased by tapering the glass, e.g. by diffraction or by increasing surface pressure stresses in the glass.

Usually, the so-called shirt-like tempering consists of the penetration of ions into the body in exchange for other ions Lower thermal expansion coefficients, with the exchange being carried out above the lower stress temperature of the glass and the oil being cooled immediately afterwards. On the other hand, surface tensions can be avoided or

Some of the relevant literature is through chemical annealing Immersion of the tempering product for a specific tent Made in a bath of a liquid treatment medium. this is, as far as we know, the usual and uniquely described process for chemical tempering »The process enables significantly improve the breaking load of the treated product and there has been a lot of research in the past few years further improvement and refinement of the bath treatment technique dedicated·

The present invention inspects calibrated to a radical departure to the conventional traversed üs has unexpectedly been found that considerable advantages can be achieved when the liquid Behandlungsaedium the product in Fora _f a continuous flow of the medium along the surface or surfaces are to be in which compressive stresses caused , EU-led.

In the bath treatment process, it is necessary to ensure a uniform composition of the liquid au, welohe in is in direct contact with the product; some of the previous research has dealt with this problem busy am related problem is to prevent the growth of the diffusion barrier at the interface, as a result of which the entry of ions into the product can be slowed down or even terminated prematurely.

By using the different technique according to this invention, these problems are avoided. Equal treatment can be achieved very easily, and the treatment is easier to regulate. In addition, the new technology makes very significant advances over the older technology in mass production. The products to be treated can when passing can be annealed in a small annealing device

The new process can ium tempering glass, vltrokrletallinam Material, ceramics or minerals are used. The procedure can be used to treat the whole product from any of these Materials or a part thereof can be applied · For example, the invention can be used for strengthening the edges or the Edge parts of a pane of glass are used * The method can also be used for the treatment of a body made of glass, vitro-crystalline material, Ceramics or a mineral which is part of a furniture, . is a coating on another fabric, can be used

In the latter case, the thinning treatment can relieve compressive stresses only in an outer layer of the exposed surface of the body cause a

Accordingly, the invention relates generally to all methods in which at least a part of a body aue glass, Vitrökrißtallinem material, ceramic or a mineral is solidified daduroh that at least a part of the body with a liquid medium of which at least one substance penetrates into the body is solidified, whereby the temperature is regulated during and near the binding rings, and thereby surface compressive stresses In this part of the body they are created or increased by being the liquid medium is applied continuously and to the Body streamed along

A uniform treatment as described by the new process is liquid, even if the delivery is uneven Treatment medium possible on the surface to be solidified. For example, when the liquid is sprayed or splashed on the surface and the liquid on the surface becomes one forms a soluble film that flows continuously over the surface, the amount of liquid escaping from different spray orifices can be slightly different without to result in a noticeable variation of the tempering effect on the individual parts of the surface »

The improved equilibrium becomes clear through the lower Number of breaks that occur during the treatment of glass panes.

the surface of the body can be blown, for example from the outside of a container in which the treatment or the gas can be distributed by means of a blower placed near the body. The gas flow or the Qaestones may be the spread of the liquid treatment medium in the form of a film over the surface or the Support the surface of the body to be treated and / or the flow rate of the liquid along the surface or the surfaces or along a certain part or Parts of it, e.g. in the case of a disk along the edge zones and the peripheral or lateral edges. So the gas can do it serve to reduce the risk of breakage for the treated article *

According to another advantageous embodiment of the process, the overflow with the liquid medium is carried out in the presence of gas flows which regulate the temperature of the treatment. The gas stream can diffusion temperatures as _s control to vary over the surface to be treated or surfaces out. The gaseous medium is Et means also possible to accelerate di "treatment characterized in that the treatment temperature is increased to a value at which the salt or other active ingredient of the liquid Behandlungsmediuiua would sereetzen when it kept a longer time at this temperature as would be the case if the liquid medium were heated or used in the form of a bath prior to application to the surface.

Advantageously, the liquid medium and the body to be treated are at least partially exposed to the action of an electric field during the flow against them. An electric field can serve to accelerate the entry of substance from the liquid medium into the body; the ion diffusion can be carried out 10 or even 100 times faster than in the absence of an electric field _e

The electric field can be an alternating fold or an alternating one Have component »With the help of such a field, the Ion exchange on two opposite surfaces one Bodies are promoted at the same time »

Advantageously, the liquid treatment medium is recovered after flowing over the body and then fed in again. A small amount of liquid is therefore sufficient to carry out the treatment Medium can occur, which would occur in the case of a tempering process like the leek process _o

The liquid medium is advantageously regenerated before it is fed back in. This regeneration is desirable because in most cases during the overflow of the treated Body hit the liquid medium, the medium becomes somewhat enriched with ions, which leave the body and become somewhat depleted in ions which are to be introduced into the body from it. The liquid one Medium is therefore advantageously regenerated thereby; that Ions originating from the treated bodies are removed and transferred to the Ions to be introduced into the body are added in the desired concentration will. Recycle and regeneration are particularly desirable in the course of an industrial bulk treatment process

The invention also includes apparatus for performing the The method described here "Advantageously, the device consists of at least one head for applying the liquid Treatment medium »a tank that the substance after overflowing the surface of the body to be treated receives and from means for holding the body to be treated in the Action zone of the mentioned head
